Despite the Swiss-born socialite being awarded $2.5 billion (Â£1.7 billion) from her former elite art dealer and horse-racing husband, Alec, in the late 1990s in one of the biggest divorce settlements in history, she claimed in the past week that she's broke.
DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.

The name DNA stands for deoxyribonucleic acid. By breaking down the name, we can understand the structure of the molecule. DNA is a long string of nucleotide units attached to one another. In a single nucleotide there are three components: 1) a sugar molecule, 2) a phosphate group, and 3) a nitrogenous base.(See Figure B-2.) In DNA, the sugar molecule happens to called deoxyribose, hence the name deoxyribonucleic acid.he name DNA stands for deoxyribonucleic acid.
